Roman gladiator cemetery found in England

Heads hacked off, a bite from a lion, tiger or bear, massive muscles on massive men -- all clues that an ancient cemetery uncovered in northern England is the final resting place of gladiators, scientists have announced after seven years of investigations.

The archeological dig has found "what may be the world's only well-preserved Roman gladiator cemetery," the York Archaeological Trust said.

Scientists have found 80 skeletons in the "unique" cemetery under the city of York, northern England, since 2003.

They announced their discoveries on Sunday, ahead of a documentary about the site due to air in Britain on June 14. This was one of two big archaeological developments, with Israeli scientists announcing the discovery of a huge cache of ancient religious objects.

They first thought the graveyard might contain the remains of criminals or political purges.
